I disagree, actually.  Having these things in a shared directory makes
it more likely that people will look at the code.  That means that
it's more likely that bugs will be found, and more likely that parts
of the code can get reused when people are doing the port to a new
chip or board.

If there were hundreds of files in arch/powerpc/sysdev then I would be
more likely to agree with you, but there aren't.

Paul.
